We can speak in the highest terms of this work, and are glad to observe that the author promises an additional volume. He engages in the undertaking with the enthusiasm that is natural in a man who is closely connected by family ties with the most distinguished alienist of the group of French physicians whose lives are recorded in the volume before us, for M. Semelaigne is the great-grand-nephew of Philippe Pinel. The author is well known and appreciated by a number of English specialists who have formed his acquaintance during his visits to this country, having been present at the Centenary of the foundation of the York Retreat, when the Association met in that city in 1892, and when he attended the Dublin Meeting this year.
